Nuclear Reactions and ALICE

Pb+Pb event
The scope of activities of our group is very broad. It reaches into both extremes of available particle energies. At CERN LHC, the ALICE Collaboration is building a dedicated heavy-ion detector to exploit the unique physics potential of nucleus-nucleus interactions at LHC energies. Our aim is to study the physics of strongly interacting matter at extreme energy densities, where the formation of a new phase of matter, the Quark-Gluon Plasma(QGP), is expected. At low energies a major experimental effort was carried out to study dynamics in binary fragmentation at masses below A=150. The two-week experiment involved over 20 scientists from 7 European laboratories. In the other demanding experiment, the shape of the fusion barrier in the reaction of 20Ne with Sn and Pb isotopes was studied. It involved 3 different registration techniques in two separate setups together with multiple energy changes of the cyclotron beam. We have also continued deep sub-barrier studies of fission and measurements of rainbow scattering. A new method, B-TOF, for energy loss of charge heavy ions has been invented and intensively utilized in 2006. The year ended with measurement of 110 MeV 4He scattered on carbon in an attempt to revile Bose-Einstein condensation properties of the second 0+ state in 12C.
